Same-sign trileptons as a signal of sneutrino lightest supersymmetric partlcle

Contrary to common expectation, a left-sneutrinos can occasionally be the lightest supersymmet- ric particle. This has important implications in both collider and dark matter studies. We show that same-sign tri-lepton (SS3L) events at the Large Hadron Collider, with any lepton having opposite sign vetoed, distinguish such scenarios, up to gluino masses exceeding 2 TeV. The jets + M ET signal rate is somewhat suppressed in this case, thus enhancing the scope of leptonic signals.Comment: Version published in Phys.Lett.

Prediction of diabetic retinopathy using health records with machine learning classifiers and data Science

Diabetes is a rapidly spreading disease. It occurs when the pancreas produces insufficient insulin or the body cannot utilise it effectively. Diabetic retinopathy (DR) and blindness are two major issues for diabetics. Diabetes patients increase the amount of data collected about DR. To extract important information and undiscovered knowledge from data, data mining techniques are required. DM is necessary in DR to improve society's health. The study focuses on the early detection of diabetic retinopathy using patient information. DM approaches are used to extract information from these numeric records. The dataset was used to forecast DR using logistic regression, KNN, SVM, bagged tree, and boosted tree classifiers. Two cross-validations are used to find the best features and avoid overfitting. The dataset includes 900 diabetes patients. The boosted tree produced the best classification accuracy (90.1%) with 10% hold-out validation. KNN also achieved 88.9% accuracy, which is impressive. As a result, the research suggests that bagged trees and KNN are good classifiers for DR

Diagnostic and statistical manual of mental disorders text revision - 5th edition: What's changed from diagnostic and statistical manual of mental disorders - 5th edition? A detailed review

The American Psychiatric Association published the text revision (DSM-5-TR) to the Diagnostic and Statistical Manual (DSM-5) in March 2022. This is an update to the 2013 publication of the original manual. The DSM-5-TR features the most current text updates based on the current scientific literature with the goal of increasing the accuracy and consistency with which clinicians make a psychiatric diagnosis (1). The following article details the changes that were made in the DSM5-TR

Recent Advances in Nanocellulose Composites with Polymers: A Guide for Choosing Partners and How to Incorporate Them

In recent years, the research on nanocellulose composites with polymers has made significant contributions to the development of functional and sustainable materials. This review outlines the chemistry of the interaction between the nanocellulose and the polymer matrix, along with the extent of the reinforcement in their nanocomposites. In order to fabricate well-defined nanocomposites, the type of nanomaterial and the selection of the polymer matrix are always crucial from the viewpoint of polymer–filler compatibility for the desired reinforcement and specific application. In this review, recent articles on polymer/nanocellulose composites were taken into account to provide a clear understanding on how to use the surface functionalities of nanocellulose and to choose the polymer matrix in order to produce the nanocomposite. Here, we considered cellulose nanocrystal (CNC) and cellulose nanofiber (CNF) as the nanocellulosic materials. A brief discussion on their synthesis and properties was also incorporated. This review, overall, is a guide to help in designing polymer/nanocellulose composites through the utilization of nanocellulose properties and the selection of functional polymers, paving the way to specific polymer–filler interaction

Visual Hallucinations in Mania

Visual hallucinations occur in a wide variety of neurological and psychiatric disorders, including toxic disturbances, drug withdrawal syndromes, focal central nervous system lesions, migraine headaches, blindness, schizophrenia, and psychotic mood disorders. Visual hallucinations are generally assumed to characteristically reflect organic disorders and are very rare in affective disorders. Here, we present a case of visual hallucinations in a young female with bipolar illness during the manic phase

Recent Advances in the Reversible Deactivation Radical (Co)Polymerisation of Fluorinated Alkenes/Acrylates/ Methacrylates/Styrenes: Editeurs: Nikhil K. Singha and Jimmy W. Mays

International audienceDue to the nature of fluoromonomers and their reactivities, specific reactions of controlled radical polymerization (CRP, or reactivation deactivation radical polymerization, RDRP) are suitable for specific monomers: fluoroolefins as well as (meth)acrylates and styrenics). For F-alkenes, Iodine Transfer Polymerization (ITP), RAFT/MADIX and reactions involving borane to some extent are the most suitable techniques. As for F-(meth)acrylates and styrenes, ATRP, NMP, RAFT and RITP have been the most appropriate methods. Industrial applications as thermoplastic elastomers have been developped for several decades. This chapter is illustrated with many examples and discussed

Defect-oriented testing and diagnosis of digital microfluidics-based biochips

Microfluidics-based biochips are soon expected to revolutionize biosensing, clinical diagnostics and drug discovery. Robust off-line and on-line test techniques are required to ensure system dependability as these biochips are deployed for safety-critical applications. Due to the underlying mixed-technology and mixed-energy domains, biochips exhibit unique failure mechanisms and defects. We first relate some realistic defects to fault models and observable errors. We next set up an experiment to evaluate the manifestations of electrode-short faults. Motivated by the experimental results, we present a testing and diagnosis methodology to detect catastrophic faults and locate faulty regions. The proposed method is evaluated using a biochip performing real-life multiplexed bioassays. 1

POSS and fluorine containing nanostructured block copolymer : synthesis via RAFT polymerization and its application as hydrophobic coating material

Herein, the nanostructured block copolymers (BCPs) of fluorinated methacrylate and POSS-methacrylate were prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization. In this case, methacryloisobutyl polyhedral oligomeric silsesquioxane (MAibPOSS) was first polymerized using 2-cyano-2-propyl dodecyl trithiocarbonate (CPDTC) as a RAFT agent. Later, the poly(methacryloisobutyl polyhedral oligomeric silsesquioxane) (PMAibPOSS) was used as a macro-RAFT agent for the polymerization of 2,2,2-trifluoroethyl methacrylate (TFEMA) monomer. The BCPs were characterized via FT-IR, H-1 NMR and GPC analyses. The BCPs spontaneously self-assembled exhibiting core-shell and lamellar type nanostructures when deposited from different organic solvents like chloroform and THF, respectively. The nanostructured morphology of the BCPs was studied using SEM, TEM, AFM, and SAXS analyses. The prepared BCPs were coated over various substrates and their hydrophobicity was measured using water contact angle analysis. The coated substrates exhibited improved hydrophobicity with the water contact angle values as high as similar to 135 degrees
